What do you do when you're worth over $8billion? You spend $450million on a luxury super yacht. Russian businessman Andrey Melnichenko has built the world's largest sailing yacht -which boasts of eight decks, a glass observation area, measures a roomy 468 feet and weighs 14,224 tons. The ship will have a crew of around 54 people, the masts are very tall, and its sails are bigger than a football field when all are flying. It will be the largest privately owned sailing yacht in the world.

The yacht, which Mr Melnichenko is thought to have named 'A' to ensure it is listed first in shipping registers, is due to begin its first sea trials later this year. Initially it will be tested with one mast before the others are fixed in place.

With an 26ft (8 metres) keel and width of around 81 feet (24.88 metres), Sailing Yacht A had to be built in one of the largest shipyards in the world in Nobiskrug in Germany.
